The fourth bevel gear 139 may be rotated by the second bevel gear 185 that is in contact with the fourth bevel gear 139. The third bevel gear 137 may be rotated by the rotation of the fourth bevel gear 139. The third bevel gear 137 may be in contact with the second bevel gear 185 to rotate the second bevel gear 185 which in turn rotates the first bevel gear 180. The first bevel gear 180 may be coupled to a second bevel gear 185 which may be coupled to the second end 125 b of the bristle roll shaft 125. There may be a first pulley 190 coupled to the first end 125 a of the bristle roll shaft 125, which may be coupled to the second pulley 192 by a belt 194. The bristle roll 124 b may be rotated by the bristle roll shaft 125 in a tilted or angled position.

FIG. 7 illustrates a rear view of an electric back scrub brush, in accordance with one embodiment of the present invention. The push button control switch 112 controls the motor 130 to start or to stop the electric back scrub brush 100 and to rotate a head 124 clockwise, counter-clockwise, in an interrupted motion, in a continuous motion or in a predetermined period of time such as approximately 5 seconds or other suitable period of time.

The rotating power of the electric back scrub brush is generated by the battery energized motor disposed in the hollow cavity of the handle. The rotating power of the motor is transferred through the spur gear system from the output end of the motor drive shaft to the central drive shaft of the neck. The electric back scrub brush includes two spur gears. The primary smaller spur gear is attached at the output end of the motor drive shaft. The secondary bigger spur gear is attached at the frontal end of the central drive shaft. The rotating power is provided to the central drive shaft through the bevel gear system causing the bristle roll shaft to rotate. The rotating power of the drive shaft transfers to the bristle roll shaft through the belt and pulley system causing the bristle roll shaft to rotate. The belt and pulley system includes two pulleys of differing diameter disposed separately from each other at the head of the electric back scrub brush. The smaller pulley is attached at the first end of the bristle roll shaft. The bigger pulley is attached at the second end of the bristle roll shaft. Both pulleys are operatively connected by a belt.

The electric back scrub brush is utilized for cleaning the back of a user's body conveniently and effectively by its rolling motion anywhere, not only in the bathroom. Because of the angle or bended feature of the head of the electric back scrub brush, it is also used as a back massage appliance.

While the present invention has been related in terms of the foregoing embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
